c23edf302b Replace PhraseMatcher with trie-based search (#4309)
* Replace PhraseMatcher with Aho-Corasick

Replace PhraseMatcher with the Aho-Corasick algorithm over numpy arrays
of the hash values for the relevant attribute. The implementation is
based on FlashText.

The speed should be similar to the previous PhraseMatcher. It is now
possible to easily remove match IDs and matches don't go missing with
large keyword lists / vocabularies.

Fixes #4308.

* Restore support for pickling

* Fix internal keyword add/remove for numpy arrays

* Add missing loop for match ID set in search loop

* Remove cruft in matching loop for partial matches

There was a bit of unnecessary code left over from FlashText in the
matching loop to handle partial token matches, which we don't have with
PhraseMatcher.

* Replace dict trie with MapStruct trie

* Fix how match ID hash is stored/added

* Update fix for match ID vocab

* Switch from map_get_unless_missing to map_get

* Switch from numpy array to Token.get_struct_attr

Access token attributes directly in Doc instead of making a copy of the
relevant values in a numpy array.

Add unsatisfactory warning for hash collision with reserved terminal
hash key. (Ideally it would change the reserved terminal hash and redo
the whole trie, but for now, I'm hoping there won't be collisions.)

* Restructure imports to export find_matches

* Implement full remove()

Remove unnecessary trie paths and free unused maps.

Parallel to Matcher, raise KeyError when attempting to remove a match ID
that has not been added.

* Store docs internally only as attr lists

* Reduces size for pickle

* Remove duplicate keywords store

Now that docs are stored as lists of attr hashes, there's no need to
have the duplicate _keywords store.

Check for relevant components in the pipeline when Matcher is called,
similar to the checks for PhraseMatcher in #4105.

* keep track of attributes seen in patterns

POS and for is_parsed for DEP

8fe7bdd0fa Improve token pattern checking without validation (#4105)
* Fix typo in rule-based matching docs

* Improve token pattern checking without validation

Add more detailed token pattern checks without full JSON pattern validation and
provide more detailed error messages.

Addresses #4070 (also related: #4063, #4100).

* Check whether top-level attributes in patterns and attr for PhraseMatcher are
  in token pattern schema

* Check whether attribute value types are supported in general (as opposed to
  per attribute with full validation)

* Report various internal error types (OverflowError, AttributeError, KeyError)
  as ValueError with standard error messages

* Check for tagger/parser in PhraseMatcher pipeline for attributes TAG, POS,
  LEMMA, and DEP

* Add error messages with relevant details on how to use validate=True or nlp()
  instead of nlp.make_doc()

* Support attr=TEXT for PhraseMatcher

* Add NORM to schema

* Expand tests for pattern validation, Matcher, PhraseMatcher, and EntityRuler

* Remove unnecessary .keys()

* Rephrase error messages

* Add another type check to Matcher

Add another type check to Matcher for more understandable error messages
in some rare cases.

* Support phrase_matcher_attr=TEXT for EntityRuler

* Don't use spacy.errors in examples and bin scripts

* Fix error code

* Auto-format

Also try get Azure pipelines to finally start a build :(

* Update errors.py

0d1ca15b13 💫 Fix bugs in matcher extensions. Closes #1971 (#3301)
* Fix matching on extension attrs and predicates

* Fix detection of match_id when using extension attributes. The match
ID is stored as the last entry in the pattern. We were checking for this
with nr_attr == 0, which didn't account for extension attributes.

* Fix handling of predicates. The wrong count was being passed through,
so even patterns that didn't have a predicate were being checked.

* Fix regex pattern

* Fix matcher set value test

483dddc9bc 💫 Add token match pattern validation via JSON schemas (#3244)
* Add custom MatchPatternError

* Improve validators and add validation option to Matcher

* Adjust formatting

* Never validate in Matcher within PhraseMatcher

If we do decide to make validate default to True, the PhraseMatcher's Matcher shouldn't ever validate. Here, we create the patterns automatically anyways (and it's currently unclear whether the validation has performance impacts at a very large scale).

ad2a514cdf Show warning if phrase pattern Doc was overprocessed (#3255)
In most cases, the PhraseMatcher will match on the verbatim token text or as of v2.1, sometimes the lowercase text. This means that we only need a tokenized Doc, without any other attributes.

If phrase patterns are created by processing large terminology lists with the full `nlp` object, this easily can make things a lot slower, because all components will be applied, even if we don't actually need the attributes they set (like part-of-speech tags, dependency labels).

The warning message also includes a suggestion to use nlp.make_doc or nlp.tokenizer.pipe for even faster processing. For now, the validation has to be enabled explicitly by setting validate=True.
